TextRange - SubCol

Hello,

I'm using template with 2 or 3 column textframe.

I'm trying to make a script that avoid hyphen at end of column.

Getting the last pgf of a column, getting the end of line type is not a problem (Constants.FTI_LineEnd).

To check if a pgf is on both column, i'm looping through my pgf to find when the textrange, i'm using, change of column.

I can only get the Id Column from the start of the pgf (pgf.InTextObj.Unique - InTextObj is a SubCol).

Is there a way to know on which column my textrange is?

var vCurrentDoc=app.ActiveDoc;
// go to last pgf of column
var pgf = vCurrentDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstSubCol.LastPgf;
// select the pgf
var textRange = new TextRange();
     textRange.beg.obj = pgf;
     textRange.beg.offset = 0;
     textRange.end.obj = pgf;
     textRange.end.offset = Constants.FTI_LineEnd;
var textItems = vCurrentDoc.GetTextForRange(textRange, Constants.FTI_String);
if(textItems.length > 0){
    vCurrentDoc.TextSelection = textRange;
     var vLineEnd = pgf.GetText(Constants.FTI_LineEnd);
     var vOriginalLine = vLineEnd.len;
     var CheckRange = new TextRange();
     var vCheck = 0;
     // to get the Id column of the pgf
     var vColNum = pgf.InTextObj.Unique;
     // no need to check last end of line = end of pgf => vOriginalLine-1
     while (vCheck < vOriginalLine-1) {
          CheckRange.beg.obj = pgf;
          CheckRange.beg.offset = (vLineEnd[vCheck].offset)-1;
          CheckRange.end.obj = pgf;
          CheckRange.end.offset = vLineEnd[vCheck].offset;
          vCurrentDoc.TextSelection = CheckRange;
// HERE is WHEREI'M STUCK
          var vColNumTR = ?????????;
// check fi column change
          if (vColNum != vColNumTR){
               // process
          }
          vCheck = vCheck +1;
     }
     vCurrentDoc.TextSelection = textRange;
}
....

Thanks in advance for the help

    #target framemaker
    var doc, pgf, textList, i;
    doc = app.ActiveDoc;
    // Paragraph containing the cursor:
    pgf = doc.TextSelection.beg.obj;
    textList = pgf.GetText (Constants.FTI_LineEnd | Constants.FTI_SubColEnd);
    for (i = 0; i < textList.length; i += 1) {
        // Look for a subcolumn end.
        if (textList.dataType === Constants.FTI_SubColEnd) {
            if (i > 0) { // Check the previous text item, which is a line end.
                // 0 = normal line end; 1 = soft return; 2 = hyphen
                if (textList[i - 1].idata === 2) {
                    alert ("last line is hyphenated.");
                }
            }
        }
    }

    The code above will tell you if the paragraph has a line that hyphenates across a sub column.

    The important thing to remember about text items when you use GetText: they always appear in document order. So when you find the SubColEnd in the list, the previous text item has to be a LineEnd, assuming that you just get these item types like line 9.

    Here is a screenshot of the document I tested it with. I put my cursor in the last paragraph of the first subcolumn.

    A simpler approach would be to do something like this. This code works on the paragraph containing the cursor.

    #target framemaker
    var doc, pgf, textList;
    doc = app.ActiveDoc;
    pgf = doc.TextSelection.beg.obj;
    textList = pgf.GetText (Constants.FTI_SubColBegin | Constants.FTI_SubColEnd);
    alert (textList.length);

    If the paragraph breaks across a column (or a text frame), then line 10 will report 2; otherwise, you will get a 0 or 1. You could wrap this in a nice function and call it in your script for each paragraph at the end of a column.

    BTW, I haven't examined each line of your code, but I know that line 9 is incorrect. The Constants.FTI_LineEnd constant is used in the GetText method and does not indicate the offset of a given line. Remember that the values of "Constants" are constant; they don't change.

    I stand corrected about one of my statements. It is possible to have a long paragraph that spans more than 2 columns, so line 10 might report 4 (or 6 or 8, etc.). So your best test would be textList.length > 1.
